SAN FRANCISCO, Sept 28 Federal antitrust regulators have asked for more information about Google Inc's (GOOG.O) planned $12.5 billion acquisition of Motorola Mobility Holdings Inc (MMI.N).
In a filing with the U.S. Securities and Exchange Commission on Wednesday, Motorola said it received a request for "additional information and documentary material" from the U.S. Department of Justice's antitrust division.
Motorola said Google also received a similar request and repeated its expectation the deal will close by the end of 2011 or early 2012.
Google, whose free Android software is the top operating systems for Internet-enabled smartphones, announced in August it plans to acquire phone-maker Motorola. (Reporting by Alexei Oreskovic; editing by Andre Grenon)
